Definitions

  • the present invention relates to a flushing mechanism for a toilet with cistern, which flushing mechanism is mounted internally in the toilet cistern, or in connection therewith, and where the toilet cistern further includes a mechanical flushing device with an activating device, together with a contact- free sensor connected to an electronic circuit.
  • the flushing mechanism according to the present invention employs the water inlet to the cistern as the motive power for activating the flushing device, which in turn is operated by the contact-free sensor in connection with the toilet cistern.
  • the flushing mechanism according to the present invention forms part of a further improvement of previously known contact-free solutions related to sanitary material.
  • One of the objects is to reduce the number of contact points for a person in a public place, e.g. a public toilet or the like.
  • sanitary material such as the operating device for a toilet flusher.
  • This may be designed in various ways, including as a push button, a mechanism which has to be pulled up, a handle which has to be turned, a handle which has to be pulled down or to the side or the like.
  • the operation of the toilet flusher thereby becomes a contact point for most users and is therefore a significant source of infection from bacteria etc.
  • Recent legislation and HMS regulations require the number of contact points where there is a risk of contagion to be restricted to a minimum, such as toilet seats and toilet flushing operation.
  • Many different solutions may be envisaged for reducing the contact between a user and the toilet flushing operation, but the best solution is the complete absence of contact.
  • the sensor may, for example, initiate flushing of urinals or the like when persons approach or more away from sanitary equipment, or the sensor may be placed in a suitable location where the user, e.g., has to block a sensor for longer than a specified period in order thereby to activate the toilet flushing mechanism.
  • the contact-free sensor activates the toilet flushing mechanism via an electrically operated device such as a servomotor, a solenoid which moves a mechanical mechanism or the like, all of which solutions have the common feature that the power consumption is relatively high, viewed over an extended period such as two or more years.
  • an electrically operated device such as a servomotor, a solenoid which moves a mechanical mechanism or the like
  • the energy consumption essentially does not involve any problems apart, of course, from the fact that it is desirable that the consumption of electrical energy when employing the solution is as low as possible. If, however, it is desirable to employ stored energy in the form of batteries, the power consumption will naturally be of interest, since it has a direct effect on the life of the battery.
  • flushing mechanism according to the present invention is further specified in the introductory part of the following claim 1, with characterising features as set forth in the characterising part of independent claim 1. Further embodiments of the flushing mechanism are further specified in the claims below.
  • fig. 1 illustrates in cross section from above a toilet cistern containing an embodiment of the flushing mechanism according to the present invention
  • fig. 2 illustrates in cross section from in front the cistern in fig. 1, with an embodiment of the flushing mechanism according to the present invention
  • fig. 3 is a perspective view of an embodiment of the activating mechanism employed in the preferred embodiment according to the present invention.
  • Fig. 1 of the drawings illustrates in section from above through a toilet cistern an embodiment of a flushing mechanism according to the present invention.
  • the flushing mechanism substantially consists of an electrically operated solenoid valve 3 with a valve housing 3'.
  • the valve housing 3' has an inlet and an outlet, which inlet is connected with a water supply 7 which may, for example, be a branch of the water supply to the toilet cistern.
  • a water supply 7 which may, for example, be a branch of the water supply to the toilet cistern.
  • the solenoid valve 3 may be replaced by various kinds of electrically or electronically operated valve devices such as, for example, magnetic valves.
  • the solenoid valve 3 in the embodiment illustrated in fig. 1 is further connected to an electronic control circuit 5 via a cable connection 6.
  • the electronic circuit 5 is further connected to an electrical energy supply via the cable connection 16.
  • the energy supply may be a stored electrical energy source, such as a battery or the energy supply may be an electrical network where the supply preferably takes place via a transformer in order to achieve the correct voltage level. Alternatively, the supply may be a low voltage network where a transformer is not required.
  • the electronic circuit 5 is further connected to a contact-free sensor (not shown) of a commonly known type which is activated by the toilet user.
  • This sensor may, for example, be an infrared or other type of sensor which, for example, is activated by holding the palm of the hand within a certain distance for a short period, thus activating the solenoid valve 3 via the electronic circuit 5.
  • the solenoid valve 3 thereby opens for a specific period (controlled by the electronic circuit 5).
  • the valve housing 3' is furthermore connected to an activating mechanism 4 via a connecting pipe 8.
  • the valve housing 3 and the activating mechanism 4 may be provided in integrated form or they may be connected via an very simple connection 8, such as a threaded pipe socket, a simple hose connection or the like.
  • the activating mechanism 4 is operated by the water jet from the outlet of the valve housing 3, and therefore in the preferred embodiment, in the transition between the valve housing 3 and the activating mechanism 4, or in the inlet to the activating mechanism 4 there is provided a nozzle which is directed towards an activating element in the activating mechanism 4.
  • the provision of the nozzle is preferred since it provides a greater capability of influencing the water flow into the activating mechanism beyond the period during which the solenoid valve keeps the valve in the valve housing 3' open. Thus the discharge velocity and the cross-sectional diameter of the water jet into the activating mechanism 4 are adjusted by the nozzles.
  • an activating mechanism is furthermore indicated in figs. 2 and 3, where a flap 13 is rotatably mounted in the housing 4 about a fulcrum 14.
  • the rotatably mounted flap 13 is mounted perpendicularly relative to the flushing direction from the nozzle at the inlet to the activating mechanism 4 and the nozzle is further adjusted in such a manner that the water jet strikes the flap 13 at a distance from the centre of rotation 14, with the result that the water jet exerts a torque about the fulcrum 14.
  • the flap 13 Under the influence of the water jet from the nozzle at the inlet to the housing 4, the flap 13 will thereby rotate as indicated in figs. 2 and 3.
  • This rotating movement is exploited, for example, by a rotating disc on the side of the housing 4 being connected to the centre of rotation 14, with the result that the rotating disc follows the rotating movement of the flap 13 under the influence of the water jet from the nozzle at the inlet to the housing 4.
  • the rotating disc 17 according to the present invention is connected via a connecting device 9 (a rigid strut or the like) with the toilet cistern's flushing device and essentially with its activating device, substantially marked 2 in figs. 1 and 2.
  • the toilet cistern's activating device for the flushing device has to be moved down in the toilet cistern, it will be natural for the connecting device 9 to be attached to the rotating disc 17 on the corresponding side as illustrated in fig. 2. If, however, the activating device 2 for the flushing device in the toilet cistern has to be moved up in the cistern, it will be natural to attach the connecting device 9 on the opposite side of the rotating disc 17 relative to the fulcrum 14 and the flap's 13 normal starting position. The rotating movement of the rotating disc 17 will thereby give an upwardly directed movement as opposed to that illustrated in fig. 2. Alternatively, the nozzle's flushing direction in the housing 4 can be altered so that it exerts a force on the flap 13 on the opposite side of the fulcrum 14.
  • the fulcrum 14 of the flap 13 may, for example, be a shaft attached on each side of the housing 4 or a kind of elastic attachment of the flap 13 on each side against the walls of the housing 4.
  • the housing of the activating mechanism 4 is provided with drainage holes for draining the water flushed through the solenoid valve 3.
  • a drainage hole 11 is provided downstream relative to the flap 13 for draining the water passing the flap 13 when water is flushed against it.
  • a drainage hole 12 for draining the water which is flushed against the flap 13 and does not pass the flap. Both sides of the flap 13 in the housing of the activating mechanism 4 will thereby be able to be drained. The drainage continues down into the rest of the cistern's water reservoir.
  • a container 10 is illustrated for sanitary fluid which is flushed as required through an aperture 15 down into the cistern.
  • This discharge of sanitary fluid from the container 10 may, for example, also be controlled by the electronic circuit 5, as indicated in previously filed patent application no. 19985945.
  • the flushing mechanism according to the present invention can be installed in a closed unit which is only connected with the water inlet 7 and is further connected with the toilet cistern's activating device for the flushing device 2, and where below the flushing device are drainage holes 11 and 12 which drain the water from the housing of the discharge mechanism 4.
  • the flushing mechanism can thereby be placed in a watertight container which also contains the necessary power supply in the form of a battery. If the flushing mechanism's electronic control 5 has to be connected to an external power source, this may be implemented via a watertight passage of a cable connection 16 which is passed on through a suitable opening in the toilet cistern to an external connection for electrical power.
